Monitoring and identifying system of household electricity utilization condition and monitoring identification method thereof

Abstract

The invention provides a monitoring and identifying system of a household electricity utilization condition and a monitoring identification method thereof. The system comprises an electric signal acquisition unit, an environment signal acquisition unit, a filtering unit, an A / D conversion unit, a control processing unit, a storage unit, a display unit, a key input unit, a communication unit, an alarm unit, and an incoming switch. The electricity utilization condition is monitored according to acquired electric signals and environmental signals. Load matching is carried out through a current harmonic coefficient of a household power grid, so as to give an alarm in time when an abnormality occurs and intelligently disconnect the wire inlet switch to ensure the safety of the household electricity. According to the monitoring and identifying system of the household electricity utilization condition and the method, the load matching is carried out through the current harmonic coefficient ofthe household power grid to accurately monitor operating conditions of each load, so as to improve safety and reliability of household electricity.

Description

technical field [0001] The invention belongs to the technical field of electric power detection, and in particular relates to a monitoring and identifying system for household electricity consumption status and a monitoring and identifying method thereof. Background technique [0002] With the continuous development of science and technology and the national economy, people's demand for electricity is getting higher and higher. In order to meet people's production and living needs, more and more electrical equipment is used by people. Household is an important part of electricity demand, because it is closely related to people's life, it is paid more attention by electricity workers. [0003] In order to ensure the quality of the household power grid, it is necessary to monitor the household electricity consumption. Traditional monitoring devices use equal-interval synchronous sampling to detect the frequency of the household grid. This sampling method cannot update and adj...

AI Technical Summary

Problems solved by technology

Traditional monitoring devices use equal-interval synchronous sampling to detect the frequency of the household grid. This sampling method cannot update and adjust the sampling points in real time when the grid frequency fluctuates, which will cause errors in subsequent data analysis and processing.
